Power up bit. This bit drives an output signal, ETMPWRUPREQ. When this signal is HIGH, power must be provided to the PTM Trace Registers. Bit [0] of the ETMPDSR indicates when power is provided to the registers.

The ETMPWRUPREQ output can be combined with DBGCOREPWRUPREQ if the PTM Trace Registers are in the same power domain as the CPU.
